A can only import f from B if f has been exported from B so while its
not a problem for A, whenever anyone issues a library(B) f will be
visible on the
search path -- the problem of potential conflicts with f remains.

B really only exported f so that A could import it but a side effect
of that is that
anyone who puts B on the search path makes f visible.
